Title: Method of inserting valve into pipeline and valve therewith
Inventor: TANABE HIROSHI
IPC: F16L55/00
Filed: 1990-04-09
Abstract: PURPOSE:To insert a valve into a pipeline without stopping a flow by installing a gate valve in the fitting of a main pipe, cutting this main pipe, attaching a plug clamper to this gate valve, opening it, and removing the gate valve and the plug clamper from each element, while inserting a stopper into a drill hole of the main pipe, and closing this main pipe. CONSTITUTION:An adapter 111 is attached to a fitting 1 of a main pipe 5 and a gate valve 7 in addition. The main pipe 5 is cut by a cutter 201 of a drill 2000 of the gate valve 7. This drill 200 is removed, and a plug clamper 38 with a plug 105 fitted with a stopper 101 is attached to the gate valve 7. This stopper 101 is held in the adapter 111, and the plug clamper 38 is removed from the adapter 111. The stopper 101 is inserted into a drill part of the main pipe 5 by an extension shaft, having it expanded wide, closing the main pipe 5. In consequence, since an excavating area of a road surface or the like and a working part of the main pipe are few, a construction period is sharply reducible.

Title: Tilt type steering device
Inventor: SATO KENJI
IPC: B62D1/18
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To permit meshing of sufficient strength even when parallelism of both meshing gears is slightly different, by forming a portion of a tooth in the facewidth direction based on ordinary gear specifications and forming the remainder of the teeth so that a predetermined clearance is formed between meshing teeth of the other gear. SOLUTION: A portion 10b of a meshing teeth 10a of a movable gear 10 is formed based on an ordinary gear specifications. A remainder portion 10c is formed with a thinner tooth width so as to form a predetermined clearance between meshing teeth of a fixed gear. Therefore, during normal use, a load applied to the meshing teeth 10a is small as long as a portion 10b formed based on the ordinary gear specifications of a movable gear 10 and the meshing teeth of the fixed gear are engaged. As a result, meshing of sufficient strength can be obtained even when the parallelisms of the movable gear and the fixed gear are slightly different, eliminating looseness thereby.

Abstract: PURPOSE:To enable manufacture of the title pipe into free dimensional structure and to contrive a reduction in production costs, by a method wherein a spiral uneven line is formed on an inner circumferential surface of a tubular molten resin by revolving a shaping roll, whose angle to an axis of the tubular molten resin is made adjustable, within a die while performing press contacting of the same against an inner circumferential surface of the tubular molten resin. CONSTITUTION:When turning operation of an operational screw 46 is performed in an uneven line forming device P, it becomes that a position of a pin 43 fitting in a groove 44 through a slide between an actuation shaft 47 and response body 45 is made variable. In other words, an angle of an axis of a shaping roll 2 to axes of tubular molten resin A, B formed through a die 14 is made variable. When the angle is made large, a range of the press contacting of a roll part 21 of the shaping roll 2 against an inner circumferential surface of the tubular molten resin A, B becomes wide. Then when a driving mechanism 3 is driven by a V belt 31, the roll part 21 of the shaping roll is revolved while performing press contacting of the same against the inner circumferential surface of the tubular molten resin A, B and an uneven line G is formed on the inner circumferential surface. However, as the molten resin A, B extruded through the die are pulled by a wind-up machine, the uneven line G becomes spiral.

Title: Preplaced brazing method
Inventor: TERADA KUNIO
IPC: B23K1/00
Filed: 1986-04-24
Abstract: PURPOSE:To suppress the compsn. fluctuation of a brazing filler metal and to execute adequate brazing with good fluidity by preliminarily coating a brazing filler metal component which is diluted by the penetration of the component from a base metal to the brazing filler metal during melting of the brazing filler metal on the joint surface of the base metal, then executing brazing. CONSTITUTION:Ni of, for example, 'Inconel 600(R)' penetrates into the brazing filler metal 4 to dilute the Au component on the joint surface in the case of brazing an outside pipe 1 and inside pipe 2 consisting of the 'Inconel 600(R)' by gold-nickel solder 4, etc. The m.p. thereof is then increased and the fluidity is deteriorated. Au is, therefore, preliminarily coated 3 on the joint surface and the brazing is executed, then the dilution of the Au at the joint surface is suppressed, the fluidity is improved and the adequate brazing is executed. The same holds true of the case in which the brazing filler metal is of silver- copper, or copper-titanium.
